Likely not the choice of the engineers, who appear not to know that they're being used as pawns in an international spy game that could send them to prison for a very long time.
I fully believe that the engineers themselves are wildly optimistic about society and their own abilities, but good security comes from realism and pessemism. Someone, probably many people, in the chain of command above them has moral and legal responsibility for choosing this course knowing it carried this risk and not caring.
Knowing their choice of targets too (definitely not left up to the engs), by which I mean only DOGEing and compromising the security of what they consider left-leaning agencies: with that targeting and their care to cover their tracks digitally, why not choose a strategy that lets the Russians in quietly? Shortly after they compromised the security of the NRLB they were making blackmail threats by taking drone videos of people (who threatened to reveal their malfeasance) where they lived and worked. Clearly someone in the chain of command is thinking carefully about what they can learn from how Russia governs
